Description

Technical Field

[0001] The present invention belongs to the technical field of relays, and in particular relates to a solid-state relay with a built-in communication function. Background Art

[0002] A solid-state relay is a contactless on / off electronic switch composed of microelectronic circuits and discrete electronic components. It uses weak current signals to control the switching of high currents. Its input can be driven by a tiny control signal, while its output can directly connect or disconnect higher current loads. Compared to traditional relays, it lacks mechanical contacts, eliminating the risk of mechanical wear and arcing. It offers advantages such as long life, high reliability, fast switching speed, and strong anti-interference capabilities. Furthermore, it is compact, lightweight, and easy to install. It is widely used in industrial automation control, household appliances, and electric heating control, providing reliable guarantees for the stable operation and precise control of various equipment.

[0003] Traditional solid-state relay control units utilize a separate, external PLC module, located outside the SSR and connected to the SSR's controlled terminals via wires. DIN-rail clip-on mounting is a common method for installing SSRs. This installation method can be categorized into two types: one employing an independent clip-on structure attached to the rear of the SSR; the other integrating the clip-on structure directly into the rear surface of the SSR.

[0004] However, a separate external control unit also requires separate installation and removal, making the installation and removal process cumbersome. Furthermore, both installation methods have significant drawbacks. First, once the solid-state relay is clipped onto the guide rail, its position is essentially fixed and difficult to move. If the installation position deviates or if a temporary adjustment is required later due to practical needs, it cannot be directly adjusted. The installed solid-state relay must be removed and reinstalled, a cumbersome process that is not only time-consuming but may also cause unnecessary damage to the equipment due to repeated installation and removal. Second, when removing the solid-state relay, a tool such as a screwdriver is generally required to pry open the latch of the latching mechanism. However, considering the aesthetics of the installation and the limited size of the solid-state relay itself, the latch is typically designed to be small and concealed, often located below the solid-state relay. This obstructs the operator's view when prying the latch, making accurate alignment difficult. Especially when closely mounted, cables from adjacent relays can become entangled with the tool, preventing the ability to apply vertical force to unlock the latch, making the removal operation extremely inconvenient and affecting overall work efficiency. In summary, the installation and removal process of existing solid-state relays is cumbersome and inefficient when in use. Summary of the Invention

[0005] The object of the present invention is to provide a solid-state relay with a built-in communication function to solve the problem of the existing relays mentioned in the background art, that the installation and disassembly process is cumbersome and the efficiency is low.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a solid-state relay with a built-in communication function, comprising a housing containing a circuit structure; the circuit structure comprising a control unit and a communication unit, the control unit being adaptively connected to the communication unit, the communication unit being configured to receive control signals from a host computer and transmit the control signals to the control unit, the control unit controlling the relay unit according to the control signals from the host computer; The rear portion of the housing is provided with an adjustment mechanism, a clamping assembly and a mounting member; The adjustment mechanism includes two cross-arranged rod structures, and the bottom of each rod structure is connected to a limiting member; Among them, one rod structure is the main driving part, and the other is the driven part; the main driving part and the driven part are connected with a connecting rod assembly; The connecting rod assembly is composed of a fixed rod portion and a movable rod portion rotatably arranged on the fixed rod portion; when the top of the connecting rod assembly moves back and forth, the fixed rod portion drives the main driving member to reciprocate and swing, and the movable rod portion drives the driven member to reciprocate and swing, and the main driving member and the driven member are arranged in a counter-swinging state; The clamping assembly is placed above the intersection of the rod structure, and the clamping assembly is lifted upward by the downward moving part of the connecting rod assembly; The mounting member is fixedly mounted on the rear portion of the housing; The adjusting mechanism and the clamping assembly are both placed on the inner side of the mounting piece.

[0007] As a preferred technical solution of the present invention, the two rod structures are respectively a main adjusting rod and a driven rod; The driven rod is the main driving member, and an adjustment slot is provided on the top of the driven rod, and the fixed rod portion of the connecting rod assembly is inserted into the adjustment slot; The main adjusting rod is a driven member, and the moving rod portion of the connecting rod assembly is rotatably connected to the main adjusting rod through the rear portion of the driven rod; The bottom ends of the main adjusting rod and the driven rod are provided with an opening for accommodating a limit piece, and the limit piece and the opening are connected by a pin, wherein the limit piece is a hook-shaped lower clamping head, which is clamped with the bottom of the guide rail and is connected by a pin shaft, which can not only ensure that the lower clamping head can rotate in the main adjusting rod and the driven rod, but also avoid separation, wherein the lower clamping head is used to clamp on the guide rail to realize the installation of the lower part of the shell; the intersection of the main adjusting rod and the driven rod is passed through a shaft rod, which is fixed on the mounting piece, and the main adjusting rod and the driven rod rotate in opposite directions around the axis of the shaft rod. In order to ensure that the main adjusting rod and the driven rod can rotate normally, grooves are provided at opposite sides of the rotation areas of the two, so as to avoid the phenomenon of obstruction and jamming of the two during rotation. In order to reflect its characteristics in the figure, the grooves provided on the main adjusting rod and the driven rod are larger than the groove length in the actual product.

[0008] As a preferred technical solution of the present invention, the fixed rod part includes a push block, a push rod and a shift rod; The push block is symmetrically provided with slots on both sides, specifically three in number. The push rod is fixed at the bottom of the push block, and the shift rod is fixed at the end of the push rod, and the shift rod is inserted into the adjustment slot; The movable rod part includes a connecting rod, a swing rod, an adjusting rod and a driving rod; The top of the connecting rod is rotatably connected to the top rear side of the driven rod by a pin; one end of the swing rod is rotatably connected to the bottom end of the connecting rod by a pin, and the other end is provided with a movable groove; one end of the adjusting rod and the driving rod are connected by a pin, and the connection between the two is concave and forms a "V" longitudinal section, wherein the angle between the adjusting rod and the driving rod is always greater than the angle formed by the intersection of the main adjusting rod and the driven rod. If the angle between the adjusting rod and the driving rod is smaller than the angle formed by the intersection of the main adjusting rod and the driven rod, the main adjusting rod and the driven rod will be affected by the adjustment when they swing in opposite directions. The obstruction of the section rod and the driving rod causes motion interference; the other end of the adjusting rod is rotatably connected to the top rear side surface of the main adjusting rod through a pin shaft, and the other end of the driving rod is in contact with the rear surface of the swing rod, and a toggle groove is provided at the other end of the adjusting rod, and a columnar body identical to the toggle rod is fixed on the top rear side surface of the main adjusting rod, and the columnar body is connected with the toggle groove through and through, and the middle part of the adjusting rod and the swing rod is also movably penetrated by a shaft rod, and the shaft rod is also fixed to the mounting piece, so as to ensure that the swing rod and the adjusting rod can rotate around the axis of the shaft rod; When it is necessary to change from the installed state to the disassembled state, the push block drives the push rod to move horizontally, and then the lever moves in the adjustment slot and pushes the driven rod to swing counterclockwise. When the driven rod swings counterclockwise, its top end rises, which drives the connecting rod to rise. Then the connecting rod pulls one end of the swing rod connected to it to rise, and then the swing rod rotates around the shaft at its midpoint. At this time, the other end of the swing rod drops. The moving slot here presses down the column on the driving rod, forcing the driving rod to move diagonally downward. Further explanation will be given in subsequent work. When the driving rod moves obliquely downward, it will press down one end of the adjusting rod. At this time, the adjusting rod will also rotate around the axis rod at its own midpoint, and cause the other end of the adjusting rod to tilt up. When the other end of the adjusting rod is tilted up, the toggle slot will drive the columnar body to move, causing the top of the main adjusting rod to be pulled inward, that is, driving the main adjusting rod to move in a clockwise direction, thereby realizing the opposite movement of the main adjusting rod and the driven rod. When the two move in opposite directions, the lower clamp will drop and release from the guide rail, and then it can be disassembled.

[0009] As a preferred technical solution of the present invention, the clamping assembly includes an upper clamping sleeve, a roller, a tension spring, and a limit bolt; The upper clamping sleeve is located above the intersection of the main adjusting rod and the driven rod, and a vertical groove is provided in the middle of the upper clamping sleeve, and the upper clamping sleeve is clamped with the top of the guide rail; The limiting bolt is connected to the vertical slot, and one end of the limiting bolt is fixed on the mounting piece, and the other end is limited and clamped on the inner side surface of the upper clamping sleeve; The tension spring is placed in the vertical groove, and the two ends of the tension spring are respectively fixed to the limit bolt and the bottom end surface of the vertical groove; and the roller rotation is set at the lower surface of the front end of the upper sleeve, and the two are connected by an axis to ensure that the normal rotation of the roller is not affected.

[0010] As a preferred technical solution in the present invention, a lifting block with a triangular cross-section is fixed on the upper surface of the driving rod, and at least two limiting columns are fixed on the surface of the mounting part; the two limiting columns are distributed on the upper and lower surfaces of the driving rod, and limit the driving rod to an inclined shape, so that when the swing rod drives the driving rod to move downward, the driving rod can move down in an inclined state under the limitation of the limiting columns, and the lifting block is against the bottom end surface of the upper clamping sleeve when it moves downward.

[0011] As a preferred technical solution in the present invention, the mounting member is a rear mounting plate, a step groove is opened on one side of the top of the rear mounting plate, the push block is placed in the step groove, and the push rod is connected to the step groove.

[0012] As a preferred technical solution in the present invention, a limit frame is also fixed on the top of the rear mounting plate, and side strips are symmetrically fixed on the inner walls on both sides of the limit frame, wherein the side strips are made of hard plastic or metal, and five through slots are opened at equal angles on the inner wall of the side strip, and a movable protrusion is provided inside each through slot, and a spring is fixed between the protrusion and the through slot, and the end of the protrusion is engaged with the slot hole on the side of the push block. The purpose of providing five protrusions is to enable the push block to perform two-stage lateral movement in the step groove. When in this stage shown in the figure, the entire solid-state relay is in the installed state, and when the push block moves a spacing H, the lower clamping head is not completely disengaged from the guide rail, and the entire solid-state relay is loose. However, it cannot be disassembled, and in this state, the lifting block will lift the entire upper ferrule, and the upper ferrule will no longer be in contact with the top of the guide rail, but it will still be in a connected state, and the roller will roll and fit with the top inner wall of the guide rail. In this state, the entire solid-state relay can be moved on the guide rail to achieve the purpose of rapid adjustment. When the push block moves from one end of the step groove to the other end, the lifting block continues to descend and no longer in contact with the upper ferrule. At this time, under the rebound of the tension spring, the upper ferrule returns to its original position to achieve connection with the top of the guide rail, and the lower clamping head is completely separated from the guide rail. The entire solid-state relay can be tilted with its back to the outside of the guide rail, and the entire solid-state relay can be lightly lifted to separate the guide rail from the upper ferrule, thereby achieving separation of the entire solid-state relay.

[0013] As a preferred technical solution in the present invention, a cover plate is also provided on the inner side of the rear mounting plate, which covers the middle area of ​​the adjustment mechanism to reduce the risk of damage from the external structure. A slot is reserved on the cover plate for the upper ferrule to move up and down.

[0014] As a preferred technical solution in the present invention, the longitudinal section of the end of the protrusion is semicircular, and the slot on the push block is adapted to the end of the protrusion, thereby ensuring that the push block can squeeze the semicircular part of the protrusion to move.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the control unit is set in the housing, and the control unit can realize the function of communicating with the host computer through the communication unit. Therefore, when installing and disassembling, it is only necessary to operate the relay itself, which simplifies the operation process. Moreover, improvements have been made to the shortcomings of the existing solid-state relay clamping structure. The improved clamping mechanism, while retaining the basic function of stable installation on the guide rail, further improves the flexibility and convenience of use. That is, after completing the initial stable installation, if the position of the solid-state relay needs to be temporarily adjusted due to actual use requirements, the operator does not need to perform tedious disassembly work. The clamping mechanism allows the solid-state relay to be moved without leaving the guide rail, and the operator only needs to perform simple operations to achieve flexible adjustment of its position; when the solid-state relay is moved to the specified position, the clamping mechanism can play the role of stable installation again, ensuring that the solid-state relay can work stably and reliably in the new position, avoiding the risk of equipment damage caused by disassembly and reinstallation, and also saving a lot of operating time. In addition, during the disassembly process, the snap-in mechanism of the present invention demonstrates great advantages. Unlike traditional snap-in structures, it does not require the assistance of any tools such as screwdrivers. Operators can easily complete the disassembly of the solid-state relay through manual operation. The whole process is simple and convenient, which effectively improves work efficiency, reduces operating difficulty and cost, and brings many conveniences to practical applications.

At this time, the push block 203 drives the push rod 203a to move horizontally. Then the lever 203b moves in the adjustment slot 205a and drives the driven rod 205 to swing in the counterclockwise direction. When the driven rod 205 swings counterclockwise, its top end is raised, thereby driving the connecting rod 206 to rise. Then the connecting rod 206 pulls one end of the swing rod 207 connected to it to rise. Then the swing rod 207 rotates around the shaft at its midpoint. At this time, the other end of the swing rod 207 drops. Here, the moving slot 207a presses down the column on the driving rod 502, forcing the driving rod 502 to move obliquely downward.

At this time, the upper clamping sleeve 202 will no longer be in contact with the top of the guide rail 300, but it will still be in a connected state, and the roller 202a will roll and fit with the top inner wall of the guide rail 300. In this state, the entire solid-state relay can be moved on the guide rail 300 to achieve the purpose of rapid adjustment. When the push block 203 moves from one end of the step groove 200a to the other end, the lifting block 502a continues to descend and no longer resists the upper clamping sleeve 202. At this time, under the rebound of the tension spring 202b, the upper clamping sleeve 202 returns to its original position, and is clamped on the top of the guide rail 300. At this time, the lower clamping head 201 is completely separated from the guide rail 300. The entire solid-state relay can be tilted with its back to the outside of the guide rail 300, and the entire solid-state relay can be lightly lifted to separate the guide rail 300 from the upper clamping sleeve 202, thereby realizing the separation of the entire solid-state relay.

The cover plate 101 covers the middle area of ​​the adjustment mechanism to reduce the risk of damage by the external structure. A slot is reserved on the cover plate 101 for the upper ferrule 202 to move up and down.

[0031] In this embodiment, the longitudinal section of the end of the protrusion 402 is semicircular, and the slot on the push block 203 is adapted to the end of the protrusion 402, thereby ensuring that the push block 203 can squeeze the semicircular part of the protrusion 402 to move.

[0032] In this embodiment, holes are provided through the upper and lower end surfaces of the housing 100 and the cover 101. Through the cooperation of the holes with bolts and nuts, the entire solid-state relay and other structures outside the guide rail 300 can be installed as needed. The holes do not contact the adjustment mechanism or the snap-on components.
